The structures with which the invention is used comprise a base 20projecting upwardly from which are standards 18, 19 and 98 which serveto support a Ahopper 110 shown in dotted lines in Fig. 1. A drum 104 isrotatably mounted on the standards 19 and 98.

A pulley. 16 is provided which may be connected -by a belt to a suitablesource of power. This pulley 16 is xedly mounted on the shaft 17 whichis journaled in the standards 18'and 19. A pinion 21 is ixedly mountedon the shaft 17 and meshes with and serves to drive the gear 22 whichserves to drive the pinion 23 through the clutch 24 operated by therockable yoke 25. The pinion 23 is in mesh with a gear 26. This une 7 7gf "65 .gear 26 meshes with the pinion 27 which is xedly mounted in theshaft 28. This pinion 27 and 90 the shaft 28 are not operative foractuating the mechanism which forms the subject matter of thisapplication, b ut serve another purpose and particularly the feedingmechanism for feeding the wire from the hopper 110. The gear 26 is xedlymounted on the stub 29 which projects outwardly from the head 30 carriedby the end wall of the rotatable drum 104 so that by a rotation of thegear 26 the drum 104 is rotated.

Positioned on beds 111 about the rotatable 3.00 drum 104 are sets offorming mechanism each set being complete in itself so that in therotation of the drum, each of the mechanisms which is complete in itselfwill pass through a complete cycle or" operation and in Fig. 2 a portionof two 10h sets of mechanisms have been illustrated, the beds 111rotating from left to right about the axis of the drum 67.

Embracing the head 30 is a bushing 31 on' which is mounted by a press t,a cam drum 32 il@ attached to the standard 19 and having a cam groove 33formed in its periphery and in which engages the stud 34 projectingradially outwardly from the push shaft 35 which is slidable in thebearing 36 mounted in the drum end Wall 104 and keyed therein by the key37 against rotation. A connection 38 serves to connect the rock shaft 35pivotally to one end 39, the other end of which is pivotally connectedto the housing 40 in which is positioned the gear 42 mounted fixedly onthe shaft 43, this gear 42 meshing with the twister gear 41 as clearlyappears in the Fig. 2. A bushing 44 is pressed into the housing 40 toserve as a bearing for the shaft 43.

The strand of wire 46 when tted onto the forming mechanism of the drum104 engages on a slot 45 formed in the forming blocks 47 and in a properposition of the drum 104 in its rotation the ends of the wire arewhipped inwardly by the arms 48.

Mounted on the bed 11'1 is a block 49 cut away as at 50 to provide spacefor reception of the clamping discs 53 and 54.v The disc54 is xedlymounted on the shaft 52 which is a driven shaft, and the disc 53 isiixedly mounted on the shaft 52 which is not a driven shaft, theseshafts projecting through a block 49. The shaft 52 is provided with areduced portion 51. Teeth 55 and .56 are formed on the periphery of thediscs 53 and 54 respectively, but only for a portion of thecircumference intermeshed as shown in Fig. 5. Each of the discs is cutaway as at 57 but the cut away portion is left at one end to provide anupstanding clamp lug 57. Guide strips 112 and 113 are provided so thatwhen the ends of the wire are whipped inwardly lby the arms 48 the endsof the Wire riding over the guide strips 112 and 113 are snapped intoposition behind the clamp lugs 57 and rest upon the face of the discs 53and 54. The reduced portion 51 of the shaft 52 and the similarly reducedportion of the shaft 52 projects through the abutment formers 58, eachof which is cut away as at 59 (see Fig. 7),

against which the wire ends are forced by the lugs 57 when the discs 53and 54 are rotated so that the wire is brought from the position shownin Fig. 6 to the position shown in Fig. 5 and in Fig. 7. An adjustingscrew 109 is threaded into the block 49 so that the abutment discs 58may be rocked on their pivot so as to vary in contour or shape given tothe wire when the same is clamped against the abutment discs by the lugs57.

The shaft 52 is locked by means of the pinion 60 which is fixedlymounted thereon and with which meshes the teeth formed on the end of thesegment bearing 61 which is rockably mounted on the sleeve 63 which isswingably positioned lon the shaft 62. Projecting from the sleeve 63 isthe arm 64 carrying the stud 65 .which engages in -the cam groove 66formed in the periphery of lthe stationary drum 67 supported by theshaft .inwardly of the slot 116 (see Fig. 2 and Fig. 10)

to adjust the relative position of the arm 61 and the boss 117. Thisconstruction is such that as the drum 104 rotates so as to carry thestud 65 incazzo@ around the drum 67 Ythe arm 64 will be rocked whichwill cause a rocking of the arm 61 and consequently through the pinion60 a rocking of the arm 52.

Prior to the sinking inwardly of the arms 48 the arm will be in theposition shown in full lines shown in Fig. 1. A neck 69 mounted on theend of the arm 70 is provided with an outwardly projecting pin 68 havingat its opposite sides the wire receiving groove 120 (see Fig. 2 and Fig.3). As the ends of the wire 46 are whipped inwardly by the arms 48 theywill end close to each other and engage the pin 68 so as to lie in thegroove 120. This arm 70 isxedly mounted on the shaft 71 (see Fig. 1 andFig. 3). A lateral arm 72 fixedly mounted on the end of the arm 71carries a pin or stud 73 which engages in the cam groove 74 formed inthe stationary drum 67.

The twister gear 41 which meshes with the gear 42 is provided with aradially extended slot 75 extending outwardly fromyslightly beyond itscenter. A cover 76 which is secured over one face of the gear 41 (seeFig. 9) is provided with a slot 75. The covered face of the gear 41 iscut away as at 77 to provide at diametrically opposite sides thesemi-cylindrical bosses 78 and 79 against which engage the concave facesof the arcuate die shoes 80 and 81, the convex of which engage againstthe projection formed in the gear 4l by the milling away referred to.Springs 82 and 1105 83 are positioned behind and engaged in a socketformed in the die shoes 80 and 81 so as to normally maintam the recess121 formed in the con- Vex surface of each of the die shoes 80 and 81thrust outwardly beyond the center of the mem- M0 ber 41. It will benoted that these recesses 121 are of such shape and size that twostrands of wire may be positioned therein side by side and closelylocked together when the die shoes are moved into center position asshown in full lines M5 in Fig. 8.

The shaft 43 is connected by the coupling 86 to the shaft 87 which isjournaled in the bearing 88 and on which is fixedly mountedthe bevelgear 87 therein. This bevel gear 87' meshes 120 with the bevel gear 89Xedly mounted on the shaft 91 which is journaled in the bearing 90 andwhich is connected with the coupling 92 to the shaft 93 on which isfixedly mounted the gear 94. A radially projected arm 95 is also fixedly125 mounted on the shaft 93 carrying an outwardly projecting roller 96which is adapted to ride on the cam plate 99 mounted on the inner faceof the standard 98. Projecting over the cam plate 99 is a guide bearing97 so that as the rotatable drum 130 104 rotates to carry the roller 96,the guide bearing 97 the roller 96 will be pressed tightly against thesurface 99. A bracket 101 is xedly mounted` on the standard 98 carryingthe segment plate 162 with which the teeth of the gear 94 may 135 engageso that at predetermined positions of the drum 104 the shaft 91 will berotated. As the gear 94 rides off of the segment 102 the roller 96 willengage the guide bearing 103 which will return it to its normal orneutral position in engagement with the surface 99. In operation whenthe gear 26 is rotated the drum will be rotated carrying with it theforming mechanism mounted thereon and in the proper position of the drum104 relatively to the hopper 110 the strand 145 of wire 46 will bedeposited in the slots 45 and securely clamped in position as therotation continues, the proper cam actuation will be effected to swingthe arm 48 inwardly to the position shown in Fig. 1. As these arms swinginwardly 150 to release the ends of the the arm will be in the position'shown in Fig. 1 and the ends of the wire will ride over the guidemembers 112 and 113 to engage behind the lugs 57 and against the surface59 and again rock the housing 40 to its original position and as theimember 41 is carried away from the location of the twisted ends of the.wire, the die shoes and 8l will move forwardly until they pass thecenter of the member 41 into open position as shown in the dottedlinesin Fig. 8. This is an important feature of the invention inasmuchas, through the twisting operation, the ends of Vthe wire are placedunder` circumferential strain resulting from the torque straintransmitted to the wire and theback lash resulting therefrom. These endswhich are engaged by the die shoes are also subject to a strainlongitudinally' of their length and by having, the die shoes open wire abinding or clamping of the twisted ends within the die is eliminated andan easy and quick release of the same therefrom effected.
